Percutaneous transluminal coronary angioscopy was performed during routine coronary angiography in seven patients and during PTCA in one patient with ischemic heart disease. A flexible fiberscope with an external diameter of 1.4 mm was introduced through an 8F or 9F guiding catheter used for PTCA into the coronary arteries. Warmed saline solution (15 to 20 ml) was injected through the guiding catheter into the coronary arteries for replacement of blood. Twenty-one of the 31 coronary segments were visualized and photographed on color cinefilms. The lumen of the atherosclerotic segment showed narrowing with smooth surface or with spiral folds. PTCA caused dilatation of the stenosed segment with scattered thin thrombi. These findings indicate the usefulness of angioscopy to observe luminal changes in the coronary arteries of patients with ischemic heart disease.
在7例患者的常规冠状动脉造影期间以及1例缺血性心脏病患者的经皮冠状动脉腔内血管成形术（PTCA）期间进行了经皮腔内冠状动脉血管镜检查。通过用于PTCA的8F或9F引导导管将外径为1.4 mm的柔性纤维镜引入冠状动脉。通过引导导管向冠状动脉内注入温热的生理盐水溶液（15至20 ml）以置换血液。31个冠状动脉节段中的21个在彩色电影胶片上被可视化并拍照。动脉粥样硬化节段的管腔显示狭窄，表面光滑或有螺旋状褶皱。PTCA导致狭窄节段扩张并伴有散在的薄血栓。这些发现表明血管镜检查对于观察缺血性心脏病患者冠状动脉腔内变化的有用性。
